摘要
To provide an ultra-high molecular weight polyolefin such as stretch-formed sheet having excellent mechanical properties and transparency, yet relatively thick SOLVED]. Density, including ultra-high molecular weight polyolefin polymer is 7dl / g or more intrinsic viscosity measured [SOLUTION] at 135 ℃ decalin solution is ultrahigh molecular weight polyolefin, the ultra-high molecular weight olefin molding of 925kg / m 3 or less melting point (Tm) below, at a temperature of room temperature or more, extending in at least one direction, thickness is 0.2mm or more, and the internal haze in said thickness direction seen the ultra-high molecular weight polyolefin stretch-formed sheet of 70% or less to prepare.
